There will never be anyone that had the effect that a Lee, Kirby, etc had because they laid the foundation and building block characters. It’s just a different industry.
In the last say 30 years, how many characters are synonymous with their creators with DC/Marvel?
Venom with McFarlane and Liefeld with Deadpool. That’s really all I can think of where it’s well known.
You don’t think of Micheline with Carnage. Or who created Harley for the animated series. You don’t think of Bendis with Miles. Etc
It’s just not the same industry anymore.
And as mentioned above Stan does get a tad more credit then he deserves sometimes as he was the poster boy for Marvel. Guys like Kirby, Ditko, etc…don’t quite get the recognition they deserve.
